FLYING TOY.

To all 'wlw-m 'it may concern: Be it known that I, ALFREDL.' SALVO,citizen of the United States, residing at Augusta, in the county ofRichmond and State of Georgia, have invented certaln new and usefulImprovements in Flying Toys, of which the following is a specificatlon.

This invention relates to toys, having more particular reference'to atoy comprlsing| a helix adapted to be projected into the air by theimparting of rapid revolving motion to the appended claims in whichthevarious novel features of the invention are. more particularly setforth.

Fig; 1 of the drawings is'a detail per spective view of my improved toy.

. Fig. 2 is a part side view and part axial sectional view thereof. A

Fig. 3 is a fragmentary axial section showing a modified form of toy.

Fig. 4 is a like view showing another modil fication.

Referring now particularly to Figs. 1 and 2 of the drawings my improvedtoy comprises a handle 10 of substantially cylindrical outline havingfixed to and projecting from its upper end, co-axially therewith, a rod11.

Freely surrounding this rod is a sleeve 12 which rests-upon the upperend ofthe handle, disengagement of the sleeve 12 from the rod 1l beingprevented by a head 13 on the rod i .which is located n an enlargementat the to rotate with the sleeve.

The helix 15 may be conveniently made of sheet metal stamped to propershape, the helix here shown being of the four bladed type, although anysuitable number of blades may be employed.

Specification of Letters Patent. Patented June 20, 1922,

Application l'ed February 1, 1922. Serial No. 583,416.

Rotation is imparted to the sleeve 12 by means of a cord 18 which iswound around a grooved portion 19 of the sleeve and is rangementI inwhich the, sleeve 12 is provided with a diminished upward projection l2aon which the helix 15 rests, the latter. being formed with a number ofradial slots 23 into which project resilient pins or fingers 24 carriedby the sleeve and presenting outwardly bowed upper portions 24 whichyieldingly hold'the helix 'on the sleeve. In this arrangement, when thesleeve is spun,

the helix is held in place until it Aattains suiiicient speed to developa lifting force 'sufficient to overcome the resistance of the sprin pins24.

In ig. 4 I have shown a further modification in which a. pairoffresilient fingers 28 are fixed at one end in the sleeve 12" andproject longitudinally outwardly through radial slots 29 therein andthrough radial slots 30 in the helix .151, having hooked free ends 28which engage over the helix andhold it on the sleeve 12b when the rodsare pressed inwardly by winding the cord 18 on the sleeve. ,V

When `the toy is spun these rods 28 remain in operative position until,the' cord is unwound, when they spring outward and release the helix.

' Having thus described my invention what I claim as new and desire toprotect byA Letters Patent of the United States is as follows:

l. A toy comprising a handle, a rod projecting therefrom, a sleeveswiveled on said rod, a helix seating on said sleeve and havingapertures through which said pins pro-` ject, and resilient fingerscarried by said sleeve and yieldingly gripping said helix to hold thelatter against axial movement with respect to said member during initialrotary movement of the helix, said helix being adapted to beautomatically disen- TQS gaged from said'fingers pressure thereof ircause nby'rdtationo'f the helix at high speed.

2. A `toy comprising a handle,a member rotatably mounted thereon, ahelix seating lof in an axial direction against the latter caused byrotation of the helix at high speed.

3. A toy comprising a handle, a sleeve rotatable on said handle, a helixseating freely but non-rotatably on said sleeve, and resilient grippingelements yieldingly engaging said helix to hold the latter` against b anaxial' direction aalnst the latter axial movement with respect to saidsleeve during initial rotary movement of the sleeve, said helix beingadapted to be automatically disengaged from said gripping elements bypressure thereof in an axial direction against the latter caused byrotation of the helix at high speed.

4. A toy comprising a handle,- a sleeve rotatable n said handle, and ahelix seatin yfreely but non-rotatably on said sleeve, an

means other than gravity holding said helix on said sleeve duringinitial rotary move' mentof said sleeve, said'means comprisin resilientfingers projecting through radia slots in said helix and engaging theslot Walls. In testimony whereof I have aixed my signature.
